Abstract
A step size is generated for use in a continuous variable slope delta (CVSD) demodulator by determining a likelihood that a group of one or more coded bits includes an erroneous bit. The step size is then generated as a function of the likelihood that the group of one or more coded bits includes an erroneous bit. For example, if the CVSD demodulator requires that the step size be increased, then the step size is increased by a larger amount if the likelihood of error is not greater than a threshold likelihood, and the step size is increased by a lesser amount if the likelihood of error is greater than the threshold likelihood.
